What is the answer to this question?

Answer:

x =1

y = 3

Step-by-step explanation:

8x - 3y = -1 ------ * 2   part (a)

-5x +2y =1 ------ * 3   part (b)

16x -6y = -2  part (c)

-15x +6y = 3        

x = 1

8(1) - 3y = -1   part (d)

8-3y =-1

-3y = -9

y =3

Answer:

2.85

Step-by-Step Explanation:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

1.5% = 1.5 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100

1.5% = 1.5/100 = 1.5 ÷ 100 = 0.015

100% = 100/100 = 100 ÷ 100 = 1

Percentage of 1.5% of what number = 2.85?

1.5% of what number = 2.85

... is equivalent to:

1.5% × ? = 2.85

1.5% × ? = 2.85 =>

? =

2.85 ÷ 1.5% =

2.85 ÷ (1.5 ÷ 100) =

(100 × 2.85) ÷ 1.5 =

285 ÷ 1.5 =

190

1.5% of 190 = 2.85

If 1.5% × 190 = 2.85 =>

Divide 2.85 by 190...

... And see if we get as a result: 1.5%

Note:

Multiply a number by the fraction 100/100,

... and its value doesn't change.

100/100 = 100 ÷ 100 = 1

n/100 = n%, any number.

Calculate the percent value:

2.85 ÷ 190 =

0.015 =

0.015 × 100/100 =

(0.015 × 100)/100 =

1.5/100 =

1.5%

So we have proven that the calculations are correct.

Answer:

1.5% of 190 = 2.85

Answer:

20=5x+2y

Step-by-step explanation:

Use the following steps to calculate closing inventory by the gross profit method:

1. Add the cost of beginning inventory to the cost of purchases during the period. This is the cost of goods available for sale.

2. Multiply the gross profit percentage by sales to find the estimated cost of goods sold.

3. Subtract the cost of goods available for sold from the cost of goods sold to get the ending inventory.

Answer:  [tex]3x^2y\sqrt[3]{y}\\\\[/tex]

Work Shown:

[tex]\sqrt[3]{27x^{6}y^{4}}\\\\\sqrt[3]{3^3x^{3+3}y^{3+1}}\\\\\sqrt[3]{3^3x^{3}*x^{3}*y^{3}*y^{1}}\\\\\sqrt[3]{3^3x^{2*3}*y^{3}*y}\\\\\sqrt[3]{\left(3x^2y\right)^3*y}\\\\\sqrt[3]{\left(3x^2y\right)^3}*\sqrt[3]{y}\\\\3x^2y\sqrt[3]{y}\\\\[/tex]

Explanation:

As the steps above show, the goal is to factor the expression under the root in terms of pulling out cubed terms. That way when we apply the cube root to them, the exponents cancel. We cannot factor the y term completely, so we have a bit of leftovers.

Answer:

  g(x) = |x -13| -7

Step-by-step explanation:

The transformation ...

  g(x) = f(x -h) +k

represents a translation h units to the right and k units up. Here, we are translating 13 units to the right and -7 units up (that is, 7 units down). Then the transformed function is ...

  g(x) = f(x -13) -7

  g(x) = |x -13| -7

Answer:

$8+x= $15.95

Step-by-step explanation:

You must subtract 8 dollars from 15.95 but because you want an equation the x is the unknown so it must be ordered like so.

Answer:

let's find the gradient first. (m)

Step-by-step explanation:

(10,3) (6,31)

y²-y¹/x²-x¹

31-3/6-3

28/3

(m) =28/3

y-y¹=m(x-x¹)

let's take y¹=3, x¹=10 and m= 28/3

y-3=28/3(x -10)

y-3=(28/3)x -128/3

taking LCM=3

3y-9=28x-128

3y=28x -128+9

3y=28x-119

Soo your equation is:

3y=28x-119

y=68°

x+y=180°

x+68°=180°

x=180-68

x=112°

Answer:

1 : 54

Step-by-step explanation:

5 men to 270 women

5 (men) : 270 (women)

make the ratio as small as you can by dividing the same number on both sides.

5 : 270. both sides can be divided by 5

1 : 54

It means for every 1 man working, there are 54 women working

Answer:

When you multiply two integers with the same signs, the result is always positive.

Step-by-step explanation:

When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative.

Answer:

  reflect it over the x-axis

Step-by-step explanation:

When g(x) = -f(x), it means the graph of f(x) has been reflected over the x-axis to make the graph of g(x). Each y-value for g(x) is the opposite of the corresponding y-value of f(x).

Answer

Yes, $237

----------------------------------------

Step-by-step explanation:

First we do $250 divided by $5 = 50 Flowers (How much they would make) but they only sell 30 flowers, with 20 left over. With $12.5 loss. Since they spent $250 and lost $12.50 on leftovers. You would then do $250 - $12.50, $237.50

Therefore making $237.50 in profit.

Answer:

g = 10

Step-by-step explanation:

(Assuming that x=1 is the first x and x=2 is the second...)

g(1) = 2(2) + 6

Simplify, g x 1 = g and 2 x 2 = 4

g = 4 + 6

Simplify, 4 + 6 = 10

g = 10

Answer:

h = 20 m

Step-by-step explanation:

So you know volume of a cylinder = π*(r^2) * h

and you also know volume of this cylinder = 180π

(volume is also in meters^3)

you can set these volumes equal to one another

180π = π*(r^2) * h

by dividing by π you get this:

180 = (r^2) * h

you need h so you can divide by r^2 to get this

h = 180 / (r^2)

now you just need to plug in the radius you are given which was 3 meters

h = 180 m^3 / (3 m^2)

h = 180 m^ 3 / 9 m^2

h = 20 m
